In 32* weather.



So, my question is, Is this any help to what my problem is? It works great for about 5 mins after a cold start (under 35-38*), then it wacks out again and acts erratic. Most of the time it'* pegged and hovers at the mark after the 3/4 mark to the end of the gauge.

Have you ever replaced the sending unit? Mine stayed peged at 120 just before it failed and poped. It started shooting a stream of oil out. It scared the ***t out of me cause I thought the block was cracked .

It was replaced already. No change. It'* possible the replacement sender was DOA.

Yeah it is possible, but it may be electrical. Have you checked the grounds, and ground busses? The cluster may be another possibility.

I have a bad sender. New. Poor quality (new). What brand was the replacement sender?

ACDelco. All grounds were cleaned. Petey (Petraman) told me he bought 2 and both caused the gauge to wack out, so I assumed it'* the cluster, BUT it is very possible he got 2 bad ones in a row. Another piece of info is that I do not have any problems whatsoever with my cluster, everything but the oil pressure gauge works flawlessly.

Hmmm, is this pressure too high? I cleaned the connections in the cluster, and now it seems to hover in this area. :?

When the car is keyed on, but not running, is the gauge bottomed out? My two AC Delco units from Rock Auto were bad, maxed out my gauge and hovered above zero when the engine wasn't running.

Nope, when the car is off, it stays at 0, and flutters ever so slightly at 0.

My bad ones fluttered too, at around 5.

If you can, test the resistance of the two pins in my thread.
